Complications of Upgrading Customized SharePoint Sites
Upgrading from the previous version of SharePoint to SharePoint 2010 is not a
trivial task, and the upgrade process needs to be planned and tested carefully. If
you are a site owner or a solutions creator of a Windows SharePoint Services 3.0 or
Microsoft Office SharePoint Server 2007 site, you might be involved in this process.
The IT department will upgrade the content so that your site runs on SharePoint
Foundation 2010 or SharePoint Server 2010. However, as the owner of the site, you
might have to decide on when to upgrade to the new look and feel and to other
customizations you or the previous owner of the site implemented.
As previously noted, SharePoint sites are different from other sites because they
use site templates during the site creation process, and these site templates point
to site definition files on the Web server. Customizing these site definition files was
easier with SharePoint Designer 2007. During the upgrade process, when Microsoft
modifies its site definitions on the Web server to include new functionality, you
might not see the new functionality, depending on the pages you customized. For
example, the ribbon is implemented as a control on the master page; therefore,
if you customized your site’s master page, the ribbon will not be available to you.
Other customizations can also affect the upgrade process, so during the upgrade
planning process you need to identify any customizations on your SharePoint sites
and test to see the effect the upgrade process might have on them.
